Today at Moscone West in San Francisco, we’re kicking off our largest developer conference of the year, Google I/O. Over two days, 5,000 people from 66 countries will hear from 200 speakers, see 180+ developer demonstrations and participate in more than 90 technical sessions, breakouts and fireside chats to meet engineers from Google and partner companies.

At last year's I/O, we demonstrated the potential of HTML5. Since then, the web has moved from a promising platform to a compelling setting for developers to build apps. This week we’ll celebrate this ongoing evolution of the web and share some of our latest work in moving the web forward and keeping it open.

Today we're announcing Google App Engine for Business, which offers new features that enable companies to build internal applications on the same reliable, scalable and secure infrastructure that we at Google use for our own apps. For greater cloud portability, we’re also teaming up with VMware to make it easier for companies to build rich web apps and deploy them to the cloud of their choice or on-premise. In just one click, users of the new versions of SpringSource Tool Suite and Google Web Toolkit can deploy their application to Google App Engine for Business, a VMware environment or other infrastructure, such as Amazon EC2.

There are already lots of great apps out on the web, but there hasn’t been one destination where you could easily find them. Our new Chrome Web Store is an open marketplace for web apps that helps people find the best web applications across the Internet and allows developers to reach new users. We also joined other web companies in announcing WebM, an open web media format project and open-sourced VP8, a high-quality, web-optimized video codec, that we are contributing to the project under a royalty-free license.

Finally, last year we introduced a new way to communicate and collaborate called Google Wave. Today we’re opening Wave to everyone — no invitation necessary — at wave.google.com, as part of Google Labs. Google Apps administrators can also enable it for their domains and help groups of people work together more productively. To learn more about this, our many new API features and more open-source code for developers, visit the Wave Developer blog.
